Research And Development Of Testing System On The Transmitting Module In Laser Fuze

Missile is important power in national defence system. As a key component of a missile, the optical module in the laser fuze transmits and receives detecting signal, its performance affects the whole weapon system. So, implementing precise evaluation of the optical module is very constructive in national defence project.We intend to develop an automatic testing system to evaluate all the parameters of the optical module in the laser fuze. There are seven parameters to be tested, including peak power, wavelength and divergence angle of the signal transmitting module and noise, response time, sensitivity and field angle of the signal receiving module. Practically, we use optical meter to test the power of the laser pulse, acquire the spectrum of the laser with spectrum instrument, use CCD method to test the divergence angle. As to the receiving module, we mainly use oscilloscope to test the four parameters. We use computer to control all the instruments and movement system to run orderly, achieving automatic testing. This project is an integrated work, which includes optical design, electrical technology, software design and precise mechanism design. The final completed system costs less testing time, maintains high precision , provides convenient operation, and achieves practical requests.The paper firstly introduces the optical module in the laser fuze and the source of the project. Then, we discuss detailed testing method of every parameter of the optical module, and determine the system scheme. We introduce how to develop and use the instruments in the system in detail. About divergence angle, the paper discusses the testing method specially. Then, we introduce the software design of the evaluation system. After that, the paper displays the experiment data and makes a brief analysis. In the end, the paper summarizes my work in the project and provides some improvement advice.
